## Discrepancy

WHILE ON APPROACH, CREW EXTENDED LG & RECEIVED NORMAL DOWN, 3 GREEN INDICATION.  THE ACFT THEN EXPERIENCED A HYD SYS FAILURE.  CREW CONTINUED ON APPROACH & LANDED, BUT BOTH MLG TIRES FAILED DURING ROLL OUT, AS THE CREWS HAD TO ENGAGE THE AIRCRAFT'S EMER BRAKING SYS.  PAXS WERE MOVED OFF THE ACFT & IT WAS TOWED TO THE FBO.  PER EVALUATION AND RECOMMENDATION FROM MANUFACTURER, MX REMOVED AND REPLACED BOTH HYDRAULIC PRESSURE SWITCHES AND THE PRESSURE TRANSDUCER.  PERFORMED HIGH ENERGY STOP INSPECTION, TASK 05-50-10-200-801A. OPS AND LEAK CHECKS GOOD.
